Detailed explanation-1: -In Maglev, superconducting magnets suspend a train car above a U-shaped concrete guideway. Like ordinary magnets, these magnets repel one another when matching poles face each other.

Detailed explanation-2: -Maglev trains use electromagnetic force to levitate several inches over the track or guideway. By eliminating a key source of friction-that of the wheels on the rails-such trains can reach higher speeds than conventional trains, have longer lasting parts, and are very quiet and smooth to ride.

Detailed explanation-3: -It is the repulsion property of these magnets which make the Maglev trains float over the tracks. As the train begins to move, the two magnets repel each other as like poles repel. When the magnets repel each other, train is held above its track and as the friction is minimised, the train can reach very high speeds.

Detailed explanation-4: -Electromagnets attached to the train’s undercarriage are directed up toward the guideway, which levitates the train about 1/3 of an inch (1 centimeter) above the guideway and keeps the train levitated even when it’s not moving. Other guidance magnets embedded in the train’s body keep it stable during travel.
